Evidently bad dry bushings probably in need of cleaning up
The internal switch is just a large set of contact points on opposite end of shaft output.
I suspect the start capacitor.
Glad you found the issue! And caps are generally a cheap fix.
A good place to try is an appliance parts store or a Heating / Cooling Parts House.
